Application filed May 27, 1903. Serial No. 158.954.

To all whom it may concern.-

Be it known that I, WILBUR N. BOWMAN, a citizen of the United States, and aresident of Pierre, in the county of Hughes and State of South Dakota, have invented a new and Improved Attachment for Linotype-Machines, of which the following is a full, clear, and exact description.

This invention relates to means for cleaning the back of the mold of a linotype-machine and protecting the slug-ejector and mold-wheel of the machine from the accumulations of type-metal calculated to interfere with the proper action of the several parts, and is designed to enable the spout of the melting-pot to make a perfect joint with the mold and prevent back squirts, which 4 cause the type-metal to escape from its proper able trouble and loss of time.

- the ejector-bla shown and described,

channel and produce -high slugs)? It is likewise designed to prevent high slugs caused by molten metal dropped in front of the ejector-blade and pressed onto the back of the slug while being ejected, also to prevent typemetal dropping onto the mold-wheel from being carried u between the mold-wheel and I e guide, thereby clogging and ing the machine and causing consider- Such objects I accomplish by means of the device herein consisting of a guard adapted to fill the open space at the top of the mold-slide, thus preventing metal from dropping in front of the ejector-blade, the end of the guard bearing against the periphery of the rim of saitLwheel, so as to scrape therefrom all accumulations of type-metal, and a wiper arranged in the path of the mold stopp adapted to oil the walls of the mold-orifice,-

thus enabling the slug to be easily ejected and a perfect lock-up to be obtainedbetween the mold and the spout of the meltingpot, thereby preventing hig slugs commonly caused by metal adhering to the back of the mold.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which drawings like characters of reference indicate views, and in which- Figurel is a perspective view of a device embodying my invention applied to a mold slide in operative relation with the rear face of a mold-disk. Fig. 2 is a side elevation of my device detached, and Fig. 3 is a top plan of a wiper forming part of my invention.

As illustrated in the drawings, a guard a,

scrapes therefrom all the like parts throughout the referably made of spring metal,is fastened y means of screws 1) or otherwise to the front end of a mold-slider. The lower'end of the guard a is curved or inclined laterally and bears tightly against the inner periphery of the rim (1/ of a mold-wheel d at the rear thereof, so that as the mold-wheel turnsthe lower end of the guard riding onthis rim accumulations of type-metal. The lower portion of the guard a is bent or inclined longitudinally, so that as the inner edge of the guard bears against the face of the moldheel the lower portion of the guard extends across the face of the wheel in a curved line, adapted to present a shearing edge to any metal accumulating on the face of the wheel and scrape such metal therefrom. The upper end of the guard a preferably projects into or nearly into contact with the rim (1 of the mold-wheel, thus constituting an effective barrier or guard against metal back-squirting from the metalot into the vicinity of the ejector and the ont end of the mold-slide.

-A wiper is applied to the rear face of the mold-wheel, and referably consists of a bent plate e, attache to the upper end of the guard a, bearing against the face of the moldwheel in the path of the mold thereof, and provided on its front or working side with a cover f,-which is preferably formed of felt or other absorbent material adapted to be saturated with oil and graphite and to ride over the rear face'of the mold as it travels in its path, thus effectually oiling the wallsof the mold-orifice, so as to prevent waste metal from adhering thereto and forming high slugs and'permitting the slugs to be readily ejected from the mold.

In the construction herein shown and described I have embodied my invention in its preferred form. I do not desire to be limited to such construction, however, as other de vices having similar capabilities may be used without departing-from my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A linotype attachment, comprising a scraper mounted to bear against the inner periphery of the rim of the mold-disk, at the rear side thereof, said scraper riding on said rim as the mold-disk turns, to remove accumulated type-metal therefrom.

2. A linotype attachment, comprising a scraper mounted to bear against the inner ing one of its ends bearing on the rim, for themold-disk, the plate having means on onev scraper being in the form of a spring-blade fastened at its intermediate portion and havpurpose specified. I

3. The combination with the mold-disk and mold-disk slide of a linotyp'e-machine, of a wiper comprising a plate mounted on the said slide and engaging the rear face of the face for carrying a lubricant, said means comprising a fabric bearing .on the mold-disk, and having'the lubricant absorbed therein.

4. The combination with the mold-disk and mold-disk slide of a linotype-rnachine, of a blade fastened to the front end of the slide and extending across the rear face of the disk to form: a barrier, substantially as described.

5. The combinationwith the mold-disk and Irold-disk'slideof a linotyp'e-machine, of a blade fastened to-Jthe front end of the slide and extending across the rear face of the disk to form a barrier, said blade being fastened at its intermediate portion and having its gntllgs in contact with the rim of the mold- 6. The combination with the mold-disk and mold-disk slide of a linotype-machine, of a blade fastened to the front end of the slide and extending across the rear face of the disk to form a barrier, said blade being fastened at its intermediate portion and having its ends in cont act with the rim of the mold-disk, and a wiper attached to the upper end of the blade in the path of the mold.

7. The combination with the mold-disk and mold-slide of a linotype-machine, of a member fastened to the slide and having one end forrring a spring-scraper bearing against the inner periphery of the rim of the molddisk, and a wiper carried at the other end of the'mold-disk in position to ride over the mold thereof, for the purpose specified.

8. A linotype attachment, con'qprising a spring-plate having one end fori'lling a scraper, and a wiper attached to the other end portion.

3 9. A linotype attachment, comprising'a spring plate having one end forming a scraper, and a wiper attached to the other I l l 11. The combination with the mold-disk of a linotype-inachine, of a guard at .the rear face of the disk for preventing the metal from dropping in front of the ejector.

12. The combination with the-mold disk and mold-slide of a linotype-rnachine, of a guard carried by the front end of the mold slide and serving to prevent the metal from dropping in front of the ejector.

13. The combination with the rncldnisk and meld-slide of a linotypenraehine, at a spring plate secured to the front end of the slide and havir'ig one-end engaging the (if the disk.
